21、The average person must think the field of artificial intelligence or AI is making great progress. The boss of a top tech company thinks that in search of creating AI that has the flexibility of the human brain, “the game is over”. Don’t be fooled. We should see it in a reasonable way. Machines may someday be as smart as people and perhaps even smarter, but the game is far from over. There is still a large amount of work to be done in making AI machines that can truly understand and reason about the world around them. What we need right now is more basic research to speed it up.
AI is making progress. Artificial images look more and more realistic, and speech recognition can often work in noisy environments. But we are still likely decades away from human-level AI that can understand the true meanings of articles and videos or deal with unexpected difficulties. The field is stuck on the same challenges that scientists have been pointing out for years: getting AI to be reliable and getting it to flexibly deal with unusual situations. Unluckily, the fact is that these systems still fail to work reliably and struggle with new situations.
Although deep learning has advanced the ability of AI machines to recognize patterns in data, it has three main disadvantages. The patterns that it learns are superficial. The results it creates are hard to explain. And the results are difficult to use in the other processes, such as memory and reasoning. As Harvard University computer scientist Leslie Valiant noted, “The central challenge in the future is to unify the formulations (统一公式) of learning and reasoning.” You can’t deal with a person carrying a stop sign if you don’t really understand what a stop sign even is.
It’s time for AI researchers to get out of turning to the media straightly for help, and ask important questions about how to build systems that can learn and reason at the same time.
【1】What does the author expect of AI?
A．It’ll make less progress.
B．It’ll get less basic research.
C．It’ll replace human workforce in all fields.
D．It’ll have the real ability to understand and reason.
【2】What does the author stress about human-level AI in paragraph 2?
A．Its cost and quality.
B．Its speech and sound.
C．Its reliability and flexibility.
D．Its appearance and operation.
【3】What is paragraphs 3 mainly about?
A．The weaknesses of AI machines.
B．The advances brought out by AI.
C．The processes of making AI machines.
D．The scientists working on AI research.
【4】What can be the best title for the text?
A．Keep Away from AI
B．Treat AI Reasonably
C．The Use of AI Should Be Reported
D．AI Is Turning to the Media for Help

Eating a big breakfast could help you burn double the amount of calories than if you eat a larger meal at dinner.
It could be the key to losing weight while also keeping blood sugar levels steady, researchers at Lübeck University in Germany said. Their study found filling up in the morning boosts a metabolism (新陈代谢) process known as diet-induced thermogenesis(DIT). DIT refers to the number of calories the body expends to heat the body and digest food. It was shown to be twice as high for those who ate more at breakfast than at dinner. On the other hand, a low-calorie breakfast increases appetite(食欲), especially for sweets, the researchers admitted.
The findings published in the Journal of Clinical Endocrinology and Metabolism were based on a laboratory experiment of 16 men. They consumed a low and high calorie breakfast and dinner one day—and then vice versa (反过来) on another. The study also showed increases in blood sugar and insulin concentrations, caused by eating a meal, was reduced after breakfast, but not so much after dinner. The results also showed eating a low-calorie breakfast caused sweet desires with a higher appetite. This suggests those saving all their calories for the end of the day may face consequences because they snack more.
The study adds to increasing evidence that the best way of losing weight is to eat your largest meal in the morning—and your smallest in the evening. Dr Richter, a neurobiologist at Lübeck University, said, “Eating more at breakfast instead of dinner could prevent obesity(肥胖) and high blood sugar.” Both obesity and high blood sugar can lead to many life-threatening illnesses including cancer, cardiovascular disease and diabetes. Previous research has shown DIT is lower in people with obesity. It’s seen as a measure of how well our metabolism is working.
DIT can differ depending on mealtime and is generally slower in the evening and at night due to our body clocks. Dr Richter said, “We recommend that patients with obesity as well as healthy people eat a large breakfast rather than a large dinner to reduce body weight and prevent metabolic diseases.”
Professor Daniela Jakubowicz, author of The Big Breakfast Diet, found that those who piled on the calories in the morning were more likely to feel satisfied, preventing snacking throughout the day. And another study by Professor Jakubowicz found that eating chocolate in the morning, when our metabolism is at its highest, prevented desires for sweet things later on.
【1】We can learn from the passage that DIT ________
A.is usually slower in the evening than during the daytime.
B.refers to the number of calories needed to heat the body.
C.has been found by the researchers in a Germany university .
D.may become twice lower when people eat a big breakfast.
【2】According to the study, eating a high-calorie breakfast can ______.
A.cause diabetes B.lead to obesity
C.keep appetite D.lower blood sugar
【3】What are the findings of the study conducted by the researchers at Lübeck University based on?
A.The observation of blood sugar changes.
B.Basic theories about diet-induced thermogenesis.
C.The data collected from a laboratory experiment.
D.Different experiments on people with different appetite.
【4】What’s the best title for the text?
A.DIT: lower in the morning or evening? B.A low or high calorie dinner
C.A big breakfast, or a large dinner? D.Less calories, better health
23、 Many cars in advertisements are red, blue or green but almost 75 percent of new cars sold are black, white, silver or gray.
A survey shows people prefer the car colors that don't show dirt such as gray. That means the owners can wash their cars less, saving money. Besides, some areas that are short of water do not allow people to wash their cars often.
According to another survey, white cars are often sold more than cars of other colors. In China, car buyers say white makes a small car look bigger. Car buyers in other countries also like white. And the research also suggests that there is a lower risk of accidents during the day for white cars compared with darker ones. People also think the temperature inside white cars is lower than that in cars of other colors.
At present, every year about 11 percent of cars sold are red and 8 percent are blue. Green has become less popular. In the mid 1990s, green was the most popular color in many places of the world. But today, green cars are hard to find.
Sometime in the future, people may not have to choose the color of their car technology may let owners change their car's paint color anytime.

24、When a group of college kids channeled their pandemic troubles into action, they never imagined the project would fuel a nationwide movement to tackle hunger and food waste.
But that’s exactly what Farmlink has done since 2020, bringing together hundreds of young volunteers to rescue nearly 77 million pounds of harvests headed for the trash and delivered them to those in need. The organization’s efforts help farmers, the environment, and people struggling to feed thef.
Launched during the height of the pandemic in spring, 2020, Farmlink was initially supposed to help struggling families and food banks. “In the United States, 40 million Americans are food insecure,” said Aidan Reilly, who co-founded Farmlink. “Meanwhile, we’re throwing out over 100 billion pounds of food every year.” Learning that local farms were forced to destroy excess produce that they couldn’t sell, especially with restaurants and schools closed, Aidan and a group of friends worked together to contact farms coast to coast.
In California, they found a farmer who had 13,000 eggs that could be donated, and Reilly offered to do the pickup and delivery himself. That was the first of many more deliveries. With “we’ll come to you” as their catchphrase, the group rented trucks and attempted to do all the food pickup and deliveries themselves.
The students ultimately got a welcome help from Uber Freight, and with the help of professional drivers, they moved more than one million pounds of produce from farms to food banks within just two months, transforming their passion project into a massive logistics (物流) operation in the process. Word spread, and more and more young people at home during the pandemic reached out to help.
Farmlink has worked with more than 100 farms and 300 communities in the US, rescuing and moving enough food to distribute more than 64 million meals.
【1】What is Farmlink?
A．A project.
B．A volunteer.
C．A food bank.
D．A college.
【2】What’s the original purpose of the Farmlink?
A．To deal with food waste.
B．To protect the environment.
C．To help with food shortages.
D．To fight against the pandemic.
【3】What does the underlined word “excess” mean in Paragraph 3?
A．Fresh.
B．Necessary.
C．Expensive.
D．Extra.
【4】What can be a suitable title for the text?
A．Transforming Passion into Action
B．Turning Food Waste into Meals
C．Distributing Meals with Joint Efforts
D．Rescuing the World from Hunger
